Resistance Calculation
Resistance Calculation is a fundamental skill in ship design and naval architecture. It involves figuring out how much force is needed for a ship to move through water at different speeds. Think of it like calculating how hard it would be to push a box across different surfaces - water creates similar resistance to ships. Naval architects and marine engineers use these calculations to design more efficient ships that use less fuel and perform better at sea. When you see this term in a resume, it shows the candidate understands how to predict and optimize ship performance.

Example Interview Questions
Senior Level Questions
Q: How would you approach optimizing a vessel's resistance for both calm and rough sea conditions?
Expected Answer: A senior candidate should explain how they balance different design factors, mention experience with various sea conditions, and discuss methods for finding the best compromise between different operating conditions.
Q: Can you describe a challenging resistance calculation project you've managed?
Expected Answer: Look for answers that demonstrate leadership in complex projects, problem-solving abilities, and how they handled technical challenges while meeting client requirements.
Mid Level Questions
Q: What methods do you use to validate resistance calculations?
Expected Answer: Candidate should mention comparing computer predictions with model tests or real ship data, and explain basic verification processes in simple terms.
Q: How do you determine if a resistance calculation result is reliable?
Expected Answer: Look for answers about comparing results with similar ships, using different calculation methods to cross-check, and understanding typical ranges for different vessel types.
Junior Level Questions
Q: What are the main factors that affect ship resistance?
Expected Answer: Should be able to explain basics like ship speed, hull shape, and water conditions in simple terms without getting too technical.
Q: Why is resistance calculation important in ship design?
Expected Answer: Should explain how it relates to fuel efficiency, ship speed, and operating costs in straightforward terms.
